The Environmental Impact Of The Great Barrier Reef

Coral bleaching is normally characterized by the expulsion of the zooxanthellae algae, loss of algal pigmentation, or both. Coral bleaching events have had serious effects on corals and reefs worldwide. What is crucial to the understanding of zooxanthellae expulsion and bleaching is how the density of zooxanthellae within the coral is changing, if at all, under the prevailing range of environmental conditions (Gates and Edmunds, 1999). Over the last twenty years, there has been a dramatic increase in both the frequency and intensity of coral bleaching events. Sixty major bleaching events have been reported between 1960 and 1979, whereas only nine were reported prior to 1979 (Huppert and Stone, 1998). Given the dependence of the coral on this symbiotic algae, it is important to determine the cause of these bleaching events. According to Helvarg (2000, p.12):

Since early 1998, climate change has been demonstrating its effects in increasing the ocean 's temperature (West & Salm, 2003). Warm water stress corals causing the phenomenon known as coral bleaching, by which expulsion of colourful symbiotic algae the zooxanthellae, vital for

The Great Barrier Reef is under threat due to many human impacts and natural impacts. These impacts lead to other consequences that may harm our society as well. For example, if the Great Barrier Reef was to be damaged by pollution, tourism levels would decrease, which can lead to a drop in the economic stance of Australia. For these reasons, it is important to keep our ecosystems safe and protected. Some of the human impacts towards the Great Barrier Reef include:

The Great Barrier Reef is iconic. It has a central place in Australian culture and psyche, and a visit to the reef is reliably rated among the top three must do experiences in international surveys. The Great Barrier Reef has continued to evoke wonder and awe in visitors, from the earliest European explorers negotiating the “monstrous labyrinth of coral” by sailing ship, to the thousands of tourists who arrive annually to experience one of the natural wonders of the world.

In the past two years, the bleachings of 2016 and 2017 have hit the Great Barrier Reef, and once again they have done horrific damage. Kerry states that the constant bleaching is concerning for two reasons: the 12 month gap between the two bleachings is too short for any coral recovery and last years bleaching was most severe in the northern part of the reef. Kerry states that last year, the temperature peak in March causes 67% of the corals to die in a 700 km section in the northern part of the Barrier Reef. This is the greatest loss of corals ever recorded in history and it’s still too early to tell if the corals will make it after this years bleaching. Kerry goes on to say that most of the bleached corals in the southern part of the reef have regained their color, meaning they thankfully survived. Kerry goes on to say there are four huge factors in the geographic patterns of the bleachings. He then goes on to give the reasons for the south surviving. To sum them up, it’s simply because the sea temperatures were close to normal during the bleachings of 2016 and 2017 in the south, the rainfall from El Nino coincided with the heat waves in 2016, and two local weather events saved the south from bleaching. Kerry closes the article by concluding that the bleachings from this year and last year will continue to unfold in the coming

The Great Barrier Reef is an iconic Australian landscape, listed by UNESCO as a World Heritage Site in 1981, being the world’s largest living organism and being one of the seven natural wonders of the world.

The Great Barrier Reef is a huge, complex ecosystem located off the east coast of northern Queensland and is considered as an ecosystem at risk. It stretches approximately 2300km from Papua New Guinea’s Fly River in the north (8⁰S) to Fraser Island in the south (24⁰S) and has become the largest World Heritage site in the world. It has 1500 of the worlds 13 000 fish species in it area, 200 bird species, 5oo species of seaweed, 600 species of echinoderm, 125 species of shark and ray and around 360 species of hard coral.

The Great Barrier Reef in Australia is experiencing bleaching. According to France-Presse, bleaching of a reef is “coral...that has been stressed by the heat” (France-Presse). When a coral has been “stressed by heat,” (France-Presse) the coral discards the algae that lives within itself which causes the coral to be more susceptible to disease. It can take up to several decades for a coral to recover from bleaching. Because of that fact that most coral does not have enough time to recover, it dies.

Marine Park Authority’s conduct an outlook report every five years which examines the Great Barrier Reef’s health, highlighting current and future pressures. This

While traveling through the spectacular continent of Australia you will find yourself discovering many local beauties.The Great Barrier Reef is the largest and most known coral reef ecosystem in all of the world. This massive reef covers over 1800 miles or approximately 2000 kilometers and thrives in the untouched and undeveloped waters of the pacific ocean. This incredible reef contains thousands of different species including coral, fish, birds, reptiles and so much more. Among many of Australia's flourishing tourist attractions the Great Barrier reef tops all others. Not only is this location a beautiful spot to look at it offers many attractions above and below the water. Snorkeling, scuba diving, fishing,

Coral reefs are threatened by global warming. They can only live in waters between 18 C and 30 C. Therefore, with the increase in temperature of the surrounding water, there has been an unprecedented increase in the number of coral bleaching events during the past 2 decades (which have had some of the warmest years in history). When ocean temperatures get too high, coral polyps lose the symbiotic algae inside them, causing them to turn white, or "bleach," and eventually die.

The Great Barrier Reef is Australia’s natural gifts. The Great Barrier Reef is the world’s largest coral reef. The Reef is located off the coast of Queensland. It is the largest living thing on Earth and even visible from outer space. The area is 348,000 km² and considered a one of the world’s heritage sites. Thousands of reefs and hundreds of islands made of over 600 types of hard and soft coral. It's home to countless species of colourful fish, molluscs and marine animals (starfish, dolphins, turtles etc.). The Great Barrier Reef is a large tourist attraction of Australia and is important to some cultures such as aboriginals. It reaches from Torres Strait to the north of Lady Elliot Island. The Australian and Queensland governments are

One of the world’s largest living structure, the Great Barrier Reef is biologically rich and diverse and is Australia’s most valued and remarkable environmental resources (Australian government). As the world’s most comprehensive coral reef ecosystem, the Great Barrier Reef is a site of unparalleled natural beauty on the north-east coast of Australia (unesco).
